THE CLEVELAND ORCHESTRA and its conductor Christoph von Dohnanyi will begin a multiyear association with Austria's prestigious Salzburg Festival in 1992, according to festival director-designate Gerald Mortier. Dohnanyi and the orchestra will open the festival in 1992, return to Salzburg in 1994, and in 1995 will have an extended residency.

Dohnanyi says the orchestra will continue its commitment to the Blossom Festival, its summer home near Cleveland. This marks the first time that an American orchestra will have an ongoing relationship with the Salzburg Festival . . . THE MINNESOTA ORCHESTRA, Edo de Waart conducting, has canceled a two-week tour to Japan in March, citing concern over the musicians' security during the present unsettled world situation.- DANCE SCENE: The American Ballet Theatre and its union AGMA have negotiated a three-year contract, good through October 1993. The dancers won few concessions in a lean year but became convinced that management fully intended to dissolve the company if their demands were not largely met. ABT at present has a $4 million debt.

Buildings: Owners of New York's Cityspire, next to New York City Center, have procrastinated building 7,000 feet of rehearsal space for dancers between the skyscraper and New York City Center. They agreed to do so in exchange for keeping the building's dome, which is nine feet higher than regulations allow.

In December the dome began emitting a high-pitched whine, which is driving crazy its neighbors for blocks around. Dancers hope it will remind owners that they promised the city three studios, to replace some of the many that have been eliminated in mid-Manhattan to make way for construction.

In February Pacific Northwest Ballet will begin a $7.8 million remodeling of the Seattle Center Exhibition Hall, a 1962 World's Fair building next to Seattle Center Opera House. The building will house company headquarters, PNB school, a dance/music resource center, costume shop and rehearsal space including eight studios. Nearly $6 million has already been raised.

The historic Perry-Mansfield dance camp near Steamboat Springs, Colo., has been put up for sale by its present owners, Stephens College of Columbia, Mo. Construction at the facility was begun in 1913 by Charlotte Perry and Portia Mansfield, Smith College graduates, who ran it for many years. It's the oldest continuously operating dance camp in the country, where many legendary dancers studied and taught. The women gave the camp's 20 buildings to Stephens in 1963. A national drive for $1.25 million is being conducted to purchase the camp. Send inquiries to the Rev. Spencer Wren, P.O. Box 772748, Steamboat Springs, CO 80477, (303) 897-1357.

- BARTLESVILLE, OKLA., is the destination of more and more music lovers every summer, thanks to the O.K. Mozart International Festival.

Quality is not at question during the nine-day event, which has grown so fast "people are killing for tickets," said Ransom Wilson, a renowned flutist and artist director of the festival. This past summer, in its fifth edition, the festival drew 30,000 spectators from 31 states.

Programs take place during two weeks in June in this northern Oklahoma town, best known as headquarters of Phillips Petroleum Co. There's an outdoor concert at Woolaroc Wildlife Preserve in the Osage Hills, but the heart of the festival is in the concert hall of the Bartlesville Community Center, an acoustic jewel.

Along with the festival comes the showcase, a gamut of displays and events that blend Mozart with the heritage of Oklahoma.

The people of Bartlesville think they have the best of two worlds - the charm of a small town mixed with the sophistication engendered by an international corporation and its many traveling executives.

String bassist Carolyn Davis of the Solisti New York Chamber Orchestra, one of last summer's attractions, finds Bartlesville unique and enthusiastic, with "a certain camaraderie."

- WHILE PRICES ARE ESCALATING for the world's art treasures, don't leave antiques out of the derby.

Barbara Johnson, wife of the late heir to the Johnson & Johnson Pharmaceuticals fortune, paid a record $15.8 million for an 18th-century Italian baroque cabinet at Christie's London auction house, making it the world's most expensive piece of furniture. The cabinet has been shipped to the Johnson home in New Jersey.

Prior to that, the most expensive piece ever auctioned was an 18th-century Newport block-and-shell secretary. It was sold last June for $12.1 million by Christie's in New York.

Purchasers have been willing to invest millions for other antiques. Examples: A Chippendale pier table recently sold for $4.62 million; a Barenholtz gilded copper weather vane for $770,000; and a Frank Lloyd Wright leaded-glass lamp for $704,000.

To draw the big bucks, an antique must be fresh to the market, come from an illustrious source, and be in a fine (not heavily restored) state ofpreservation. Ironically, furniture from the lowly and austere Shaker sect is among the most highly prized. Collectors recently paid $154,000 and $91,300 for three-legged Shaker candlestands at a Boston auction.

- THE TRISHA BROWN DANCE COMPANY celebrates its 20th anniversary year with two commissioned premieres, a double New York season, and performances in major American and European theaters. In September the company danced a Brown world premiere, "Foray Foret," at the Lyon (France) Biennale de la Danse. Further performances were in Berlin; Antwerp and Nimes, France; then in Columbus, Ohio; and Miami.

The new work will lead off the company's anniversary season at New York's City Center in March, followed by concerts at the Whitney Museum and the National Gallery in Washington, D.C. As part of the AT&T dance touring program, the company will visit Pittsburgh; Minneapolis; Helena, Missoula and Billings, Mont.; Denver; and Norfolk, Va.

- THE DANCE NOTATION BUREAU of New York has entered the computerized world with a system that promises to revolutionize the recording of dance steps on paper. In this system, developed at Ohio State University, the computer essentially becomes a "word processor" for the complex symbols of Labanotation, accurately recording in graphic form steps, body movements, floor plans and rhythm of any dance, just as the choreographer intended.

In the past, notators have arduously written down by hand movements that can now be interpreted by one computer symbol. Its innovators expect the system to dramatically reduce the cost of permanently recording and preserving dances.

- ARDIS KRAINIK, general director of the Lyric Opera of Chicago, continues to run her company in the black and blaze new trails.

"We haven't had a deficit since 1981, and for the second year in a row our entire season was sold out by opening night," said Lyric spokeswoman Susan Mathieson. "Our ticket sales will top $11 million. Our fund-raising goal for the year is $7.95 million, and we're right on target for that, too."

Meanwhile Krainik works her "Toward the 21st Century" plan, showcasing overlooked 20th-century opera works and encouraging new composition.

This season she programmed "The Voyage of Edgar Allan Poe" by Dominick Argento, in full production, well received. Other forward-looking works include "McTeague" by William Bolcom in 1992-93, based on the same story as Erich Von Stroheim's silent movie epic, "Greed."

The Lyric plans a complete Wagnerian Ring, one opera a year beginning in 1992-93, capping off with all four operas in the spring of 1996. World premieres of two other operas will occur in 1996-97 and 1999-2000, both by American composers.

- THE LARGEST INTERNATIONAL LOAN EXHIBITION of Fauve art ever presented will be on display at the Metropolitan Museum of Art in New York, Feb. 19-May 5, 1991, and in a reduced version at the Royal Academy of Arts in London, June 10-Sept. 1.

The exhibition, "The Fauve Landscape: Matisse, Derain, Braque, and Their Circle, 1904-1908," consists of 175 paintings from public and private collections in the United States, Europe, the Soviet Union, Israel and Japan.

They reflect five years in the history of French art when the Fauves, literally "wild beasts," created works of daring innovation in form and color. The show, which previously was in Los Angeles, is funded by Ford Motor Co., with additional support from the National Endowment for the Arts.

- THE SPOLETO FESTIVAL USA 1991 will celebrate the 80th birthday of its founder, Gian Carlo Menotti, with 29 commissioned works among the 123 events now planned. The festival will take place in Charleston, S.C., May 23-June 9.

Though Menotti, who is also artistic director, will not be 80 until July 7, the celebration will be early. Among special events will be a revival of Menotti's opera "Maria Golovin," and Rostropovich will conduct Menotti's cello concerto. Musical America has selected Menotti as musician of the year.

The festival has a budget of $5.7 million, the most ever, for such events as a new production of Monteverdi's 1642 opera, "L'Incoronazione di Poppea," Offenbach's "Tales of Hoffmann," England's Rambert Dance Company, Balinese dancers, and an outdoor symphony-with-fireworks finale.
